Dynasty Fantasy Baseball Stock Watch: Pitching Prospects to Monitor

We typically focus on the big leagues when discussing fantasy baseball, but are going to also help out those of you in dynasty/keeper leagues with some minor league updates throughout the year.

We'll cover minor league hitters and pitchers who are excelling in stories today. First, let's focus on minor league pitchers - check back for the article on hitters.

I'm only going to include players age 25 or younger. Let's get to it!

JR Ritchie - Atlanta Braves

Ritchie is the No. 82 prospect in baseball. He's off to a fast start at Triple-A, and is expected to be called up at some point in 2026.

He's 3-1 over four starts and 21 1/3 innings. Ritchie has allowed just three runs on 12 hits and 10 walks, while striking out 20 batters.

Ritchie has looked good in his minor league career, and it probably won't be long until he gets a crack at the big leagues. Keep tabs on him and be ready to add him in some redraft leagues when he gets the call. Ritchie is worth stashing in dynasty/keeper leagues, as he has a very bright future.

Eli Jones - Minnesota Twins

Jones isn't a top-30 prospect for the Twins. That could change if he keeps pitching as well as he has to start 2026.

In 15 innings across three appearances at High-A, Jones has a 1.20 ERA. He has allowed three runs (two earned) on five hits and one walks, while striking out 12 batters.

Jones had a 5.13 ERA over 23 appearances at Single-A last year, so it makes sense why he's not a highly-touted prospect. Things can change, and the 22-year-old appears to be on the rise. He's one to keep tabs on, but only stash him in the deepest of dynasty leagues right now.

Bradley Blalock - Miami Marlins

Blalock isn't a top-30 prospect for Miami, but that's because he has too much MLB experience. He first made his MLB debut in 2024, and he's logged 89 1/3 innings overall, but has an 8.16 ERA.

The 25-year-old is at Triple-A right now, and has a 1.93 ERA over 14 innings pitched across three outings. Blalock has allowed three runs on eight hits and five walks, while striking out eight batters.

With MLB experience on his side, Blalock is on the team's 40-man roster, so all it might take to get him back to the big leagues is an injury. Blalock could also force his way up with more strong outings in the minor leagues.

We'll see if he can ever break through, but for now, only owners in really deep dynasty leagues should be rostering Blalock.

Chase Petty - Cincinnati Reds

Petty is the Reds' No. 7 prospect. He has covered 16 1/3 innings and has 22 strikeouts already, but he has an ugly 6.61 ERA too.

Petty has allowed 12 runs on 18 hits and five walks. He's made four starts, and is 1-2.

He pitched six innings across three MLB appearances in 2025. Petty allowed 14 runs (13 earned) so he started this year at Triple-A. He just turned 23 years old, so he has time to still emerge as the highly-touted prospect he is.

Petty likely will need to lower his ERA before he gets called back up. He's definitely one to keep an eye on, and roster in most dynasty leagues still.

Robby Snelling - Miami Marlins

Snelling also has 22 strikeouts to his name so far. He's pitching in Triple-A and has made three appearances.

Snelling has allowed four runs on seven hits and eight walks over 13 innings, which equates to a 2.77 ERA. He is 0-1.

Snelling is the No. 35 prospect in baseball and is expected to be called up sometime in 2026. He's definitely one to roster in dynasty leagues, and one to watch for when he gets called up. That should happen at some point this season, and maybe somewhat soon if he keeps pitching well at Triple-A.

Jake Brooks - Colorado Rockies

Brooks isn't a top-30 prospect for Colorado. He has 20 strikeouts in just 11 innings pitched at Double-A.

In two appearances, Brooks has allowed just one run on six hits and a walk. It's the big strikeout total that should stick out to you.

Brooks is 24 years old, and if he keeps pitching well, he could push his way into the big leagues at some point in 2026. He has a career 3.21 ERA in the minor leagues, so I'm a bit surprised he doesn't crack the Rockies' top-30 list.

Keep tabs on Brooks, but for now, he's not a huge dynasty asset.

Payton Tolle - Boston Red Sox

Tolle is the No. 16 prospect in baseball. He made seven big league appearances in 2025, covering 16 1/3 innings. Tolle was 0-1 with a 6.06 ERA, so the Red Sox sent him to Triple-A to start the 2026 season.

Tolle has 19 strikeouts over 15 innings pitched. He's 2-0 over three starts, and has allowed eight runs (five earned) on 12 hits and four walks.

Tolle should get called back up at some point in 2026, although it might take an injury to get him there. Boston's starting rotation is stacked, so that works against Tolle.

The 23-year-old has a bright future, and needs to be rostered in all dynasty leagues.

Kade Morris - Athletics

Morris is the Athletics' No. 12 prospect. He is working in Triple-A, and has a 2026 ETA.

Morris is 1-0 over three starts, and has a 3.94 ERA. He's allowed seven runs on 18 hits and six walks over 16 innings. He's struck out 14 batters so far.

The 23-year-old has a career 4.39 ERA in the minor leagues, so he looks more like an average fantasy pitcher in the long run, but you just never know how a prospect will perform once they reach the big leagues. He's a name to keep tabs on, but he's a lower-level dynasty asset for now.

Coleman Crow and Tate Kuehner - Milwaukee Brewers

Crow is the No. 27 prospect for Milwaukee, while Kuehner isn't in the top 30. Both guys have worked 15 2/3 innings over three appearances, so they are built up and ready to be called up if need be.

Crow is 2-0 with a 4.02 ERA so far. He has allowed seven runs on 16 hits and five walks, while striking out 18 batters.

Kuehner has a 4.60 ERA and 1-0 record over his three appearances. He's allowed eight runs on 15 hits and six walks, while striking out 13.

Both pitchers are 25 years old, and could be called up if injuries hit, or if members of the MLB team's starting rotation struggle. Milwaukee has a ton of pitchers to turn to, so it could be tough for Crow or Kuehner to get called up in Milwaukee. Their best chances to reach the big leagues could come via a change of scenery.

These two pitchers are ones to keep tabs on. We'll see if they ever get MLB opportunities, at which point they'll have some fantasy upside. Right now, both guys are very low-level dynasty assets.
